โœฆ Synopsis


A single-step calorimeter has been used to measure the energy relations involved in the room temparature tensile deformation of single crystals of copper. The dam have been discussed in terms of theories of work hardening. The values of the stored energy were linearly related to the square of the shear stress, the constants of proportionality being orientation dependent. sought in terms of the dislocation structure after deformation. An explanation of these effects has been ENERGIE STOCKEE DANS DES MONOCRISTAUX DE CUIVRF On utilise un ealorim&re B un &age pour mesurer les &changes d'energie impliques dans la deformation de traction de monooristaux de cuivre & temperature ambiante. des theories de la consolidation.

The rate of diffusion of antimony in copper single crystals has been measured over the temperature range 600'1OOO'C by means of a sectioning technique employing the Sblz4 radio-isotope as tracer. The diffusion activation eneigy and frequency factor were found to be 42000 & 700 cal mole-l and 0.34 5
